CULTIVATO R.

SPECIFICA'IIONl forming part of Letters Patent No. 253,458, dated February 7, 1882.

Application filed October 13, 1881.

have invented certain new and useful Improvements in Straddle-Row Cultivators; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon,whicl1 form a part of this specification.

This invention relates to straddle-row cultivators, and has for its object to furnish a sulky which can be used without the use of a tongue or other similar pole extended from the axles to the breasts of the horses.

It consists in a substantial frame which passes under and to the rear of the axle, and is made fast to the latter and to the arch, and is provided with a cross-bar, which passes under the forward end of the cult-ivator-beam, and has its forward end extended and provided with means for holding the whiffletree.

In the drawings, Figure l is a perspective of my invention, and Figs. 2 and 3 are detail views of parts thereof.

a a' are the spindles or axles which carry the wheels. The inner end of axle a is bent to a vertical position, so as to provide the standard a2, and is also bent horizon tally to provide the top cross-bar, a3, which extends over the row of corn. The axle a' has its inner end bent to a vertical4 line, so as to provide a standard, a, parallel with the standard a2. The standard a4 has formed on its upper end an eye, a5, which slides over the end of the top bar, al. The sides of the head or upper end of standard a4 are attened, as shown in Fig. 2, and the ears of the clips, hereinafter described, project along these attened sides and hold the standard to its position, and yet permitthe standard to have a slight rocking motion on the arm a3. The top bar, a3, may be made rectangular or round. I prefeito make it round, so that the eye will turn thereon. The standard a4 is secured to thel top bar, a3, so that it will swing slightly forward and back, and thus give a reciprocating movement between the two standards, so that there will be an adaptation or ad- (Model.)

justment to the slight variations which take place between the draft of the two horses.

In my device I provide two clips, c c, con` structed to slide over the bar a3, and flattened to fit snugly against the opposite sides of the eye a5 and hold the latter, so that the standard a4 will have the requisite swinging movement. The clips are held'by pins c2,which are put through suitable holes and through holes formed in the cross-bar a3. A series of holes are provided in the cross-bar a3, so that the eye a5 may be moved and fixed at any desired place, and thereby set the standards a2 and a4 nearer together or farther apart, as may be required.

d is the supporting-frame, which is composed of the main straight bar d and the lat-eral bar d2. rIhe main bar d has its forward end arranged in proper position to have a whifletree hooked thereon. The rear end of this bar passes under and several inches to the rear of the axle a, and is made fast to the latter by clips or other suitable fastenings. The lateral bar d2 has its forward end secured near to the forward end of themain bar, while its rear end is carried to and past the inner side of the standard a2, and is made fast to the latter by a clip, as shown. The ends of the bars d d2 which project to the rear of the axle are connected together by a cross-bar, d3, thus completing thel frame d. The cross-bar d3 passes v rbeam is fastened. l

The coupling f is journaled on the axle a and has on its top a slot, through which projects a pin or st-ud,f, iixed on the axle. The slot and pin are arranged so as to permitalmited turning movement to the coupling, which movement permits the cultivator to be lifted over obstructions. The clevis has in its rear end a horizontal slot, in which is pivoted the foI'-, ward end of the beam c, thus'giving thelatter a lateral swinging movement. It will be seen that the weight ofv the beam e rests on the cross-bar d3.

When the horses are attached to the front end of the frame d the counter-balance between the draft-of the horses and the weight of the cultivators holds the arch of the sulky in an nprightposition. When standing still the arch IOO will be held erect by the Weight of the forward end of the' frame', counterbalanced by the Weight of the cultivators.

I have described only one frame, el. It will be seen that I employ two frames; but both being alike in construction and arrangement, the one description will answer for both.

It will also be seen that the arch of the sulky is composed of the standards a2 a4 and the cross-barca, united together adjustably, ushereinbefore described.

The supporting-wheels of the suiky havebeen omitted in the drawings,in order that the other parts may be more clearly brought to view.

It will be seen that I have here provided a substantial sulky for straddlerow cultivators and have dispensed with a tongue.

Having thus described my invention, what claim, and desire to secure by Letters Patent'4 is"- l The'combination ofthe axle,provided with pin f', the coupling f,journaled on said axle, and provided with slot f2, the beam @,pivoted to the coupling` f, and the cross-bar d3 of the frame d, extended under and arranged to support the rear end of the coupling, substantially us set forth.

2. The combination, substantially as hereinbefore set forth, of the arched bar a3 of axle a, provided with a series of vertical holes,the upright bar a4 ot' axle a, provided with eye a5, and the clips c, provided with parallel ears projected part Way across the flattened sides of bar a4, and the pins 02, as set forth.

In testimony whereof I afx my signature in presence of two Witnesses on this 10th day of October, 1881.

J AGOE WILLIAMS.
